# Catalog Model

> How capabilities, providers, and provider endpoints are presented in the Unified API.

# Workbench Model

The Unified API Workbench is organized around three human-facing objects:

* `Capabilities`
* `Providers`
* `Endpoints`

## Capabilities

Capabilities are the default lane.

Use them when you want DumplingAI to standardize the job and keep the request shape simple.

## Providers

Providers are vendor overview pages.

Use them when you know the supplier you want and want to browse everything Dumpling exposes for that provider.

## Endpoints

Endpoints are provider-native operations.

Use them when you want exact provider behavior and provider-specific output, rather than DumplingAI's normalized abstraction.
